Refusal to operate |
The AFDD circuit breaker
is not connected to the neutral wire, causing refusal to operate |
The AFDD circuit breaker is only
connected to the phase wire on the power side and the neutral wire is not connected. |
Connect the neutral wire on the power
side. |
|
False tripping |
The AFDD circuit breaker trips due to a short circuit | The line (L) and neutral (N) wires
at the incoming and outgoing terminals of the AFDD circuit breaker are crossed |
Strictly follow the wiring diagram and
the product markings to correctly connect the circuit. |
